Description: The present invention relates to cyclohexanediurea derivatives which potently lower cholesterol and thus are useful as effective medicines for hyperlipidemia, atherosclerosis, etc. Lipometabolism disorders in hyperlipidemia, atherosclerosis, etc. are considered to be a risk factor which closely relates to cerebral apoplexy, myocardial infarction, etc. Recent research has shown that cholesterol is esterified before its intestinal absorption and that the esterification of cholesterol is also necessary for its accumulation on the endarterium or in the liver. It has been further elucidated that the enzyme which catalyzes the esterification of cholesterol is Acyl-CoA : cholesterol acyltransferase (hereinafter referred to as "ACAT"). Since the compounds which inhibit the activity of ACAT can inhibit the esterification of cholesterol, these compounds are expected to prevent the intestinal absorption of cholesterol or cholesterol accumulation on the endarterium and are considered to be potential medicines for hyperlipidemia and atherosclerosis and various diseases caused by them. Conventional ACAT enzyme inhibitors can be classified on the basis of chemical structure into three groups: amido derivatives (JP-A-23848/1988 and 278038/1990), urea derivatives (JP-A-6455/1990, JP-A-294256/1991 and JP-A-220168/1991) and diurea derivatives (JP-A-203360/1989 and JP-A-117651/1990 and EP-B-325397). However, there has been no report of diurea compounds in which urea groups are linked to a cyclohexane ring via alkylene chains which is the chemical structure to which the present invention relates. In search of a new ACAT enzyme inhibitor more powerful than those of the prior art and effective as a medicine for conditions such as hyperlipidemias and atherosclerosis, the present inventors studied 1,2-, 1,3- and 1,4-positions on the cyclohexane ring and cis- or transisomers of diurea compounds in these positions and finally found that certain isomers of cyclohexanediurea derivative fulfill the above-mentioned requirements. The present invention accordingly provides a compound which is a cyclohexanediurea derivative of formula (I): wherein R 1 and R 2 are the same or different and each is a straight-chain or branched alkyl having at least 3 carbon atoms, cycloalkyl, cycloalkyl having a bridge head, furyl, furylmethyl, furylethyl, furylpropyl, furylisopropyl, furylbutyl, furylisobutyl, furyl sec-butyl, furyl tert-butyl, furylpentyl, furylisopentyl, furyl tert-pentyl, furyl neopentyl or aralkyl, A 1 and A 2 are the same or different and each is phenyl, pyridyl, quinolyl, isoquinolyl or indolyl, each of which is unsubstituted or substituted; or a salt thereof. The present invention also provides a cyclohexanediamine derivative of formula (II): wherein R 1 and R 2 , which are the same or different, are each a straight chain or branched chain alkyl group having at least 3 carbon atoms, cycloalkyl, cycloalkyl having a bridgehead, furyl, furylmethyl, furylethyl, furylpropyl, furylisopropyl, furylbutyl, furylisobutyl, furyl sec-butyl, furyl tert-butyl, furylpenty, furylisopentyl, furyl tert-pentyl or furyl neopentyl; or a salt thereof.

Pharmacological Test Examples Compounds of the present invention were tested for their pharmacological effects by the following methods. 1) Inhibitory effect on ACAT (Acyl-CoA : cholesterol acyltransferase) enzyme (No.1) Compounds of the invention were tested for their inhibitory effects on ACAT enzyme of rabbit liver microsome by the method of J.G. Heider (J. of Lipid Res., vol. 24, 1127-1134, 1983). More specifically, the test was done by measuring the amount of labelled cholesterol oleate ester produced from oleic acid CoA (coenzyme A) labelled by radiation. Table 1 shows the concentration of each test compound needed to inhibit 50% of the enzyme activity of the control group.

Microsomes of the liver and small intestine mucosa were prepared by the method of C. Marco et al. (Biochim. Biophys. Acta, 617, 458-471, 1980). ACAT enzyme activities of the microsomes were determined by the method of J.G. Heider (J. Lipid Res., 24, 1127-1134, 1983). A test sample dissolved in 1% dimethylsulfoxide was added to a microsome fraction (100 µg), a phosphoric acid buffer (0.154 M) having pH 7.4, 1- 14 C-oleoyl CoA (36 µM), dithiosleitol (2 mM) and bovine blood serum albumin (36 µg/ml). The reaction mixture adjusted to a final capacity of 0.5 ml was incubated at 37°C for 60 minutes. A mixture (6 ml) of chloroform and methanol (2:1) was added and the reaction was stopped. Cholesterol oleate was extracted with chloroform and separated by thin-layer chromatography. ACAT enzyme activities of the microsome fractions were determined by radiation measurement. Table 10 shows the results.

The cells were then monolayer-cultured with 80 ml of each medium containing 10 µg/ml of cholesterol and 5 µg/ml of 25-OH cholesterol in a 175 cm 2 flask for 5 hours. The homogenizes of these cells were subjected to centrifugation at 105,000 g to collect microsome fractions. ACAT enzyme activities of the microsome fractions were determined by the above-mentioned method. Table 11 shows the results.

A 6-week-old SD-type (Sprague-Dawley) male rat was fed with food containing 1% of cholesterol, 0.5% of cholic acid and 5% of olive oil for 2 days and then orally administered the food and a compound of the invention as dissolved in saline once a day for 5 days starting on day 3. Four hours after the final administration, a blood sample was taken. The total cholesterol in the serum of the test group was measured and compared with that of the control group. Table 2 shows what percentage of the cholesterol in the serum of the control group was reduced by means of the test compound.

[3-2] Using a rat having high cholesterol, compounds of the invention were tested for their serum cholesterol lowering effects by the following method. A 6-week-old SD-type (Sprague-Dawley) male rat was fed with food containing 1% of cholesterol, 0.5% of cholic acid and 5% of olive oil for 7 days. For the last 5 days, a test sample suspended in some drops of Tween 80 and saline was orally administered once a day. Four hours after the final administration, a blood sample was taken from celiac aorta of the rat under etherization. The total cholesterol in the serum of the test group was measured by the oxygen method and compared with that of the control group. Table 13 shows what percentage of the cholesterol of the serum of the control group was reduced by means of the test compound.
